| Abstract: | In this paper we suggested the importance of sea ice edge in our country's sea ice monitoring and forcasting.The sea ice edge is the boundary between water and ice.Monitoring of sea ice edge's position and the change is vital to sea water exchange,marine fishery,nearshore marine operation,offshore oil-gas exploration,meteorological observation and so on.The conventional method of sea ice edge extraction often has the shortcomings of massive mixed spots existing and the slow computation speed.Clustering is a... |
